I was measuring from O’Hare Airport, the closest point.
Yeah, well, O’Hare is an example of the city reaching out beyond its “natural” boundaries to grab a valuable piece of real estate.
Everyone I know measures from the Loop. Seems reasonable enough.
In any case, we agree, it’s suburban, not Chicago.
State ‘n’ Madison is zero for Chicago. St.C North is about 38 miles west of there.
